FRUIT-DRIER.

SPECIFICATION forming part of Letters Patent No. 257,409, dated May 2,1882.

(No model.)

'Z`o allwhom. "it may concern:

Be it known that I, JAMES M. TnAsDALE, of Howell, in the county ofLivingston and State of Michigan, have invented an Improvement inFruit-Driers, of which the following is a specification.

The nature of this invention relates to certain new and usefulimprovements in the construction of lfrnit-driers wherein the trayswhich contain the fruit are placed between flues through which steampasses, such ues being situated one above the other. The heat radiatingis designed to evaporate the moisture which the fruit soexposedncontains; and it is especially designed as an improvement uponLetters Patent granted to me for the same purpose October 26, 1880.

The invention consists in the peculiar construction of the flue endsthrough which communication is provided for the passage of steam fromone due to another, and whereby the same can be shipped from the factoryin the knock-down" condition and be readily put together or put up atthe place where it is designed to operate the same, all as more fullyhereinafter set forth.

Figure I is a perspective view of my improved fruit-drier. Fig. 2 is avertical longitudin-al section through the same, and Fig. is aperspective of one of the section ends detached and separated.

In the accompanying drawings, which form a part of this specification, Arepresents a suitable steam-generator, which may be provided With afurnace beneath it, or it may be designed, when built in the smallersizes, principally to rest upon thel top of an ordinary stove, thefunction of said generator being merely to generate steam for supplyingthe series of flues which surmount it, for the purpose hereinafter setforth; and as such furnace forms no part of my invention, I will confinemyself exclusively to describing the construction of my evaporator.

`B represents a series of flues, substantially as shown, the alternateends of which are connected together, adjnstably or otherwise, by an endline, C, which will admit of steam passing from one flue to the other,asin a vertical coil, while the opposite alternate ends of these flnesin the series are supported by a proper Wall, D.

In the construction of driers designed for family use this device may beconstructed substantially in the manner as described in'rnyaforementioned Letters Patent; but Where the same are designed for usein factories upon a larger scale it has been found expensive in point oftransportation in manufacturing and shipping them in their Whole stateready for operation. Hence the object I have in view is to so constructthe device thatit may be built in section at the factory and shipped ina knocked-down state to the point where itis designed operating it, andWhere it may readily and easily be set up; andto this end I constructthe endflues, C, in sections-that is, they are centrally longitudinallydivided and provided with fianges a.. Each one of these sections is thenrigidly secured to the open end of the flue I, or such end may beconstructed so as t o form an integral part of such flue, and when thedevice is set up the flanges a of the ends C come coincident to eachother, having a rubber or other gasket placed between them, and aresecurely bolted together by means of bolts b, thus forming a continuoussteam-passage froin the-lower to the upper flue in the chamber.

If desired, one end of the evaporating-pan may be constructed deeperthan the opposite end, so that dry hot steam will pass to the system ofdues, which construction would naturally cause said flues to dip in adirection toward the shallow end of the generator, and these lower endsof the flues in the series may, if desired, be provided with drip-pipesseparately or to discharge any one common pipe which shall convey theWater of condensation in the flues back to the generator below theWater-line. p

In Fig. 2 are shown separate drip-pipes, which preferably should beconnected to the fines from the outside. While I show the end dues asmade in only two sections, it may he advisable, particularlyin largedriersz, to have these sections provided with detachable ends.

Where a considerable number of dues are employeditmay be foundadvantageous to supply a separate steam-pipe, E, which shall deliversteam from the generatorinto one of the end sections at or about halt'the height of the device for the purpose of supplying fresh live steamto eoininingle at that point with the steam which has already passedthrough the coils beneath, thus enhancing the evaporating capacity ofthe upper tlues; and such pipe, for the matter ot' convenience inillustrating, I represent as applied to a device wherein are employedbut four lues above the generator.

The fruit to be dried is placed upon suitable drawers, (not shown,)which are placed between and upon the series of lines, the heat which isradiated from such iiues evaporating the moisture contained in the fruitand discharging the same at the open sides, as in the ordinary manner.

While I show and describe a steam-generator situated beneath the seriesof iues, I do not wish to confine myself to its use, as in manyinstanees steam may be applied to the device from a steam-generatorwhich supplies steam for other manufacturing purposes.

What I claim as my invention is` 1. In afruit-drier, and in combinationwith the main lues thereof, end ilues made in sections detachable fromeach other and adapted to receive the ends of the main iues,substantially as and for the purpose specified. Y

2. In a fruit-drier, and in combination with the series of steam-dues B,the end ues, C, provided with the anges aand designed to be securedtogether to form a steam-connection between two adjacent lues B,substantially as and for the purposes specified.

3. In a fruit-drier, and iu combination with the end tlues, (l, andgenerator A, the tlues B, provided with drip-pipes for the purpose ofconveying the water of condensation back to the generator from said iuesB, substantially as described.

4. In a fruit-drier, and in combination with the detachable end lues orsections, C, the lnain flues B and the walls D, as and for the purposespecified.
